Abstract (en)
A motor-integrated fan having an intake port and a blow-out port comprises a rotary part 12 that is rotatably supported by a shaft, and a motor 14 that rotates the rotary part 12. The motor 14 is an outer periphery drive motor that rotates the rotary part 12 by supplying motive power from a duct provided on the outer peripheral side of the shaft. The motor 14 includes: a permanent magnet 45 provided on a rotary support ring 33 connected to the outer peripheral side of blades 32 of the rotary part 12; and a coil 46 provided opposite the permanent magnet 45 in the axial direction of the axis of rotation. Among the plurality of blades 32, a first blade 32a and a second blade 32b are located at different positions in the axial direction.
